CONSTRUCTION In general Referring now'more particularly to' Figs. 1 to 4 of the accompanying drawings, there is illustrated an apparatus, in this instance a gasoline ling station of the so-called visible type, 'comprising what may be termed a series of four sections of compartments or levels numbered 1 to 4 respectively. The first, third and fourth levels have floors, separating the level more or less completely (as the ease may be) from the level below. In the first level 1 are located the inlet and overflow pipes from and to a reservoir (not shown), the gasoline pump and drive there- .for, quantity stops, a stop handle and gearn the second'level 2 is mounted the operating handle, discharge valve, discharge passage, hose, the drain valve and draining passages, the lock, and mechanism associated with these several parts.

In the third level 3 is mounted a container, quantity indicators, a surrounding protecltive screen, supply pipe, distributor head,

overfiow pipe, and an emptying weir.

In the fourth level 4 is a downwardly refleeting dome encasing electric lights, and surmounted by a translucent bulb containing an electric light -and used for illuminating or advertising purposes or both.

For convenience the four levels will be considered separately.

First level (Figs. 4, 5, 6' am] '7) lzontally into the right rear of the machine and runs forwardly to the L 18 and thence vertically from said L, to the gasoline pump 22, then up from the discharge side of the pump, through the first and second levels and to the third. In the third level an inlet pipe I receives gasoline flow from the piplllhe overflow piping 24 extends horizontally into the left rear of the machine and runs forwardly to the \L 16, and thence vertically from said L through the first and seeond levels and to the third. The overflow pipe O passes gasoline to said overflow piping 24.

he gasoline pump 22, which 1s preferably of the rotary type is mounted on a lplatform 26. This platform is clamped to the vertical i inlet and overflow pipes 20 and 24, and to the vertical wiring conduit 28 through which Coning 34 is-mounted on a sub-easing 35 which last named casing encloses the junction box and L castings. The casing 34 lias-means for opening it, in order that the first level may be easily examined or entered for repairs. The L castings have their respect-ive vertical pipes threaded therein and stufling boxes 36 provided at the threaded portions. rI`his construction permits of adjustment of the vertical pipes without consequent leakage, in so far as the stufiing boxes may be tightened after an adjust-ment.

A vertical brace 38 for the upper levels is housed within the casing of the first level 1.

Quantity stop rofl (zml quantity control rod brackets Below the plhnp bracket 26 and fastened to the same uprights which liold said pump bracket namely, the pipes 20, 24 and 28, is a lower hori'fzontal bracket 40.

Above the pump bracket 26 and fastened to the pipes 2O and 24 is another horizontal bracket 42 (seegFigs. 14 to 16, and 24 to 26).

The Quantity szfop mechanism Figs. 5, 6', 8,

1;?, and 24 t0 ,26'

Between the horizontal brackets 40 and 42 in first level 1 are mounted'a vertical stopshaft 44 and a vertical control shaft 46.

The stop-shaft 44 is borne in bearings 48 and 50 of the lower and upperlbraekcts 40 and 42 respectively. 1

Thel control shaft 46 is borne in bearings 52 and 54 of the lower and upper brackets 40 and 42 respectively. j

The bearingst 48, 50, 52 and k54 are of one type, comprising, (see Fig@ 6), a threaded adjustable scket 56 screwed to the bracket "and locked to said bracket by means of nuts 58. The socket carries the ball end 60 of the shaft borne therein.

The quantity stop shaft 44 andcontrol shaft 46 are mounted vertically between said brackets and -are geared at their lower ends by means of sector gears 62 and 64. The latter gear 64 is on the control shaft. The gears are pinned to their respective shafts. By means of the gears (52 and 64 rotation of the control shaft 46 causes opposite rotation of the quantity stop shaft 44.

The stop shaft 44 carries fastened thereon, properly spaced brackets or quantity stops' .titl

ved portion 84, in such 0', 1', 2', 3', 4', 5', 6', 7', 8', 9', 10', spaced in sequence downwardly. In the present embodiment there are eleven stops although the number may vary to suit a given station capacity. rlhis station will deliver a maximum oi' ten gallons withone filling.

' 'lhe quantity stops are spaced vertically,v

as described. lVith regard to lateral spacing, each quantity stop, belore fastening it to the shaft 44 in its required horizontal plane, has been rotated out of the vertical plane of the one above it. This rotation has been of such an amount as to throw the ends of the stops out et interference in vertical projection or plan. (See Fig. 12.)

'llhe ends ot' the stops are provided with flat headed adjustable bolts 66, in order that wear may be compensated for, and adjustments easily made. y Y

The stop shaft 44 carries thereon alsol a horizontal arm 68 which in turn carries the arcuate strip 70. This strip carries thereon numberswhich correspond7 when registering with a hole 72 in the forward side of case '1 34. with the number of gallons of gasoline being delivered oi about to be delivered.

The controlshaft 46 is provided with a longitudinally slidable shoe 74 (Figs. 5, 6 and 12),. The shaft 46 is rotatable within a bearing 7 6 of said shoe 74. A heel 7 8 of said shoe cooperates with any one of the said eleven quantity stops that happens to be set in the vertical path of said heel. The shoe 7 4 is kept trom turning by means of its fastenings (bolts to a vertically slidable weir strip 82. The function of thestrip 82 will be described later.

Embracing the upper and lower ends of the slidable shoe 74 are the forked portions' 84 of the adjusting handle 86. Thehandle 86 and portions 84 are slidably mounted on the control shaft 46 but not rotatably mounted thereon. Rotation is prevented by means of a key-wheel 88 pinned within the upper forka manner as to extend into a longitudinal key-way 90 of the control shaft 46. f

rllhe adjusting lhandle 86 extends horizontally forward and out through a slot 92 provided inthe casing 84. The lateral width ot the slot 92 is such as to permit the handle 86 to take the dotted line positions a: and shown in Fig. 12. The slot 92 is of such vertical length that the handle 86 may, by means ot its forked portions. be permitted to carrv the shoe 74 and heel 78 past any possible point of stoppage by the stops 0', 1', 2',

- 3', 4'. 5', 6'. 7". 8', 49'., and 10. Numerals 94 beside the slot 92 indicate numbers of gallons ot' gasoline dispensing, or to be dispensed when the handle 86 is at a given elevation.

Second Zei/'eZ (Figs. M to 17; 19 to 2] and@ 250V 26' inclusive) lhis comprises a more or less flat casting 98 and 17). Y

Passages and drain cul/vel The casting 100 is provided with a passage 106 which serves to establish communication between the overflow pipe O screwed into the top of said casting 100 (extending up into the third level) and the overflow piping 24. (SeeFigs. 14 to 17). The casting 100 is bolted to the casting 102 as well as to casting 98. The overflow passage 106, of casting 100, communicates by means of a branch passage 108 with a branch passage 110 of casting 102. (Fig. 17).

Between the casting 102 and the flat casting i v98 is interposed a flange or plate 112 to which i is fastened, by soldering or a like method, a discharge tube D. The discharge tube D passes downwardly through a passage in the casting 98 and communicates with a rectangular discharge passage 116 of the casting 02. A passage 114 in the flange 112 permits this communication. (Figs. 14 to 17 Beneath the casting 102 is fastened a depending casting 118 with a discharge passage 120 therein. The passage 120 communicates with the passage 116 of casting 102 and'com municates with a discharge valve 122 by means of a nipple 124.

A bypass 126 in casting 4102 permits communication between the third level and discharge passage 116. In this by-pass 126 is located a drain valve 128 which is operable to make or break the by-pass communication between the third level and the discharge passage 116.

The drain valve 128 comprises a passaged.

guide spider 130 which guides the valve 128 to its seat when said valve is closing. Valve 128 is fastened to a valve stem 132, and when not forcibly pullt'd from its seat, is held closed by means of spring 184. The valve stem 132 passes forwardly of the pump and out throiurh a self adjusting stuiiing gland 136. An adjustable follower 188 is screwed to the outer end of the valve stem and locked in position by means of a lock nut. The 'follower 138 is provided with a disclshaped head 140. (Figs. 15, 21 and 22).

The castinglr 104 (Fig. 17') has a passage 142 therein which establishes communication be tween the. filling pipes 20 and the gasoline inlet pipe I of the third level.l Both inlet and overflow pipes I and O pass through passages inthe casting 98 and screw into the castings 104 and 100 respectively..

Adjustable wez'r blades-Passing vertically through the casting 102 is the slidable Weir blade 82 already mentioned in lconnection with the first level 1. This blade 82 cooperates slidably with the discharge tube D of the third level 3 and is fastened to the shoe 74 in the lirst level 1. By means of the shoe ist . embrace the weir blade.

74 the blade is raised and-lowered. In passing through the casting 102 the blade is packed against leakage of gasoline by means ofa s)tutling box 14'2. (Figs. 14 to l5` and 24 to 26 Stuffing bow 142 (Figs. 14150 17'l and 24 to 26') passage thru the packing at the level of in- .This piece 156 is placedopposite sertion of said gratings. This level coincides with the level of the branch passage 110. Below the .packing 154 is a spacer piece 156. a subpassage 158 leading-from. the branch passage 110. Below the spacer piece 156 is laced more packing 160 and beneath this pac ing 160, the packing follower 162. Thepacklng follower 162 is adapted, by means of studs and nuts 164, to properly force the recited elements of the stuffing box together.

The Weir blade is provided with a lateral row 166 of {iveholes so placed that when said blade is in its uppermost or night drain position, said holes align with' the openings l 152 in the gratings 148 (Figs. 16 and 26) and when said blade is in its zero or neutral position said holes align with the opening provided by the spacer piece 156, (Figs. 15

and 24). x

vA casing 159 interposed between the casting 98 and casing 34 serves to substantally enclose the recited parts of the second level 2.

The zack handig H (Figs. 1r. w 16, ze, a3 @mi l comprises an approximately ring shaped castlng 17 2, on opposite sides of which are provided handles 175 for purposes of operation. The casting 17 2 swings relatively on the huh 4178 for a limited distance l(Fig. 23). Its ring shapesurrounds the dischargevalve. Thehub 178 is keyed 'to a shaft 180 and is provided with a flange 182 rearwardly thereof. Cn the forward end of thehub isplaced another flange 184 which seats on a chamfered portion of the hub and is held thereto by a nut 186 threaded to the shaft 180'. The ianges 182 and 184 are provided with oppositely drilledisets of holes I 188 and 190 respectively spaced 180 degrees apart.

Two larger holes 194'are drilled, (in positions corresponding to the recited holes) in the hub portion 192 of the operating handle said holes 188 and 190, thereby causing an easily broken clutch connection between the lock handles and the shaft 180. The recited device is, in fact a light-load clutch and will be designated as clutch- C hereinafter. V

The shaft 180 is the pivot shaft of the discharge valve 122. This valve 122 is of the gate type and the shaft 180 operates the gate 200 (Figs. 14, and 19 to'21) to open and shut positions. l Therefore the handles 175 of the casting 172 will open and shut the gate valve 122 if turned clockwise and counter-clockwise respectively. On the upper side of the casting 172 is formed a cam 202 (Figs. 19 to 22) which comprises a slot 204, guides 206 and wedge shaped cani surfaces or fingers 208 sloping toward and under the head 140 of the drain valve follower 138. The enlarged head 140 of the follower is adapted to fit between the guides 206 and be pulled forwardly from its extreme drain closed position by means of the fingers 208 as said fingers swing counter-clockwise around the pivot shaft 180 as center. The guides 206 and the fingers 208 are integrally cast. This counter-clockwise Inovement incidentally closes the discharge gate valve 122. Bringing forward the follower 138 obviously opens the drain valve 128.

Beside the clutch C there is a lost motion engagement between the casting 17 2 and the pivot shaft 180. This comprises a iin 210 (Figs. 19 to 21) fitted to the casting 172 adapted to cooperate with either end of a relatively long notch 212 cut in the edge of the forward ange 184. When the pin cooperates with-the right hand edge of said notch.212 the clutch C is engaged,(Figs. 19

and 23). When the pin cooperates with the left edge of said notch the clutch is disen-. gaged, that is, the balls 196 are free of their holes 188, 190 and ride easily on the flanges 178 and 184. e

The function of the lost-motion movement of the pin and slot is to permit the drain valve to close before the discharge valve opens 1 handles 175 in so face 230 of said rod 222. This is due to the Widt insana' angular lead of the cam 102 is converted to lag on the counter-clockwise movement of the far as the closed clutch C holds the pin 210 against the right-hand end of the slot 212 on the said counter-clockwise movement. See Fig. 20. At the end of said movementy lthe seatingl ofthe gate valve, and continuing action ofthe handles l17 5 counterclockwise, again opens the light-load clutch C (Fig. 21).

lawaloca (Figa. 14' a 16,19 to c1, z5 aaa ce) The handle casting 172 is provided on its lower side with a hole- 214 which, when the handles are in night or neutral position, is adapted to cooperate with a rod 216 borne slidably in depending bearings 218 and 219 of the casting 118. The rod 216 is normally held toward the rear of the pump with a pinned collar 220 forced against the rearward depending bearing 218 by the spring 222 which reacts against the forward depending bearing 219.4 In locked position the rod'216 is pulled forward (Fig. 16) so that a hole 224 drilled laterally therein 1s brought outside of the casing 34. In this position a padlock may be locked on the rod 216 by means of hole 224, thus preventing the rod from returning to normal position. The hole in the case 34 through which the rod 216 passes will not admit the padlock. l

The rod 216, in viewing the pump from the rear normally interferes with the Weir blade 82 at the edge thereof. A notch 226 is cut in the rod, whichvvhen the rod is in discharge or zero-neutral position, will permit the Weir blade 82 to move up and down. (Figs. 14 and Aflat faced cam 228 fastened to the Weir blade is adapted to hold the rod 216 in such a position as to cause it to enter the hole 214 of the handle casting and at the same time permit travel of the Weir blade vertical- The cam 228 cooperates with a sloping 216. .The weir blade can move verticall when the rod 216 rides on the cam 228 an when said rod is pressed rearwardly in its unlocked osition by spring i of the notch 226. l/Vhen the rod 216 is pulled forwardand into locked position inthe handle casting l 17 2, the notch 226 goes out of register with the plane of the Weir blade 82 and to provide for its movement forward a notch 232 is cut into the Weir blade (Figs. 25 and 26). Of course the rod 216 can move forward to locked position only when the notch 232 registers with the rod 216. The notch 232 is adapted to register with rod 216 only when the Weir blade is i-n its highest position, or when holes 166 are in line with the grating holes 152.-

The inlet pipe I', stands vertically within the container beneath the deector 246 and is screwed into the casting 104.

The overflow pipe O, stands vertically within the container and is screwed into the castingvlOO (Figs. l0 and 17). This pipe is made adjustable in length by means of the cap 248 screwed thereon. The cap 248 is kept aligned by the ring 250 and has its downward adjustment limited by the lugs 252. The length of this pipe is made such that it will permit a level of gasoline Ain the container up to the zero marking of the indicators 243. igs. 9 and 10.)

Tae dac/Large pape D (Figs. 18, er, aaa a5) is preferably of rectangular section and stands vertically in the container K. It is soldered or otherwise fastened to the flange 112 and communicates with the discharge. Stay bolts or rods 254 are provided to keep its shape. This pipe D is open along its length on one side. The-op osite sides of the opening 256 are provide with babbitt lined grooves 258 within which slide the sides ofthe Weir blade 82. The said lining may be replaced by any suitable provided a seal is maintained between the Weir blade and pipe D. The pipe Dfreaches above the level of the overflow pipe O.

The siphon-breaker SB ermits, by means of branch A, air to enter e container K as liquid descends therein and permits, by means of branch B, air to enter the discharge side of the discharge valve 122. (Figs. 9 and 17).
